Understanding the physics and origin of the width-luminosity-relationship of SN Ia light curves is an important aspect
in the modeling of SN Ia [1]}, [2]}, [3]}, [4]}, [5]}, [6]}, [7]}, [8]}. Brighter SN Ia often have broad light curves that decline
slowly after peak brightness. Slightly less bright or dimmer SN Ia have
narrower and relatively rapidly declining light curves. In addition, several SN Ia do not follow the width-luminosity-relationship (e.g., SN 2001ay, 2004dt, 2010jn, SCC, CL and SN 2002cx-like SN Ia), which reinforces the notion that a significant number of physically relevant factors influence the diversity of SN Ia overall (see [9]}, [10]}).
